SWING.

To all 'whom it may concern:

Beit known that I, JOHN F. HARTMAN, of Fond du Lac, in the State ot'Wisconsin, have invented a new and useful Lever-Swing for the Exerciseand Amusement of Children; and I do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying' drawing, forming' a part of this specication, and to theletters of reference thereon marked.

The drawing is a perspective View of my improved invention.

My invention consists in the peculiar construction of a swing consistingof a swinging' seat supported from a gallows-beam connected to a seriesof levers in such a manner that the child sitting' in the seat can takehold of the rope hanging from the vlever device, and by properly pullingand slacking the rope can swing himself more easily than in the conrmonswing.

In the drawing, A represents a light portable gallows-frame, from whichthe swing depends. B is a strong bar pivoted so as to oscillate inbearings in the uprights A.

l is the swingseat, secured to the swingbars D D. These bars arefastened into the oscillating bar B.

E is a short strong' lever, projecting` about one foot to the rear ofbar B, to which itis rigidly attached.

F is the long operating-lever, about two and a half feet long, pivotednear the middle to a short stud, G, upon the cross-bar A of the frame,and is always parallel to the lever E.

His a connecting1 lever between the rear ends of levers E and F, and isalways parallel to the stud G.

I is a rope hanging from the front end of the operating-lever F down toand opposite the seat G.

Although the drawing shows the seat as suspen ded and operated from aportable frame, A. I do not intend to limit myself to the use of such aframe. The operating apparatus can be suspended from brackets secured tothe ceiling. It is contemplated, however, to make and sell the combinedframe and swing in a portable form.

The operation of my invention is extremely simple. The child sitting inthe seat takes hold of the rope in such a way as to throw his weightforward upon the front end of lever F, depressing it and raising rearend of lever E, thereby carrying the seat backward. A s the swingreaches its farthest point backward the rope is slacked and the swinggoes forward. Ihen it reaches the farthest point forward another pull ofthe rope assists in throwing the seat backward.

. By this device a person using the swing' can amuse himself more easilythan in any swing known to me.

Having' fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination and arrangement of bar B and swing-bars D D with thelevers E, F, G, and H, and rope I, substantially as and for the purposesset forth.

JOHN F. HARTMAN.
